This study was conducted to define the effects of light transparent rate of the shading on the photosynthesis ability of the ginseng leaves and their seasonal changes. Regardless the effects of light transparent rate of shading and age of ginseng plant, 10,000 lux was the most adequate light intensity for the maximum photosynthesis of ginseng leaves and seasonal difference was not significant. The ginseng plants which were grown under 10 to 15 percent light transparent shading showed the highest photosynthesis ability. The photosynthesis ability of ginseng leaves was significantly decreased in September than June and the decreasing rate was higher at the ginseng plants planted on back rows than front rows. In June, the ginseng plants grown under 10 to 15 percent light transparent shading showed high respiration amount but in September, those grown under 20 to 25% light transparent shading showed the highest respiration. The amount of chlorophyll of ginseng leaf was significantly decreased by increasing light transparent rate of shading.
